Speciiicatign forming part of Letters Patent No. l 73,494, datedFebruary 15, 1876; application filed April 14, 1875.

To all lwhom it may concern:

Be it known that I, HIRAM PURDY, of Burlington, county of Des Moines andState of Iowa, have'invented a new and useful Improvement in the Art of'Odorating a Pure `Spirit and other substances 5 7 and I do herebydeclare that the following is a full, clear, and

exact description thereof', reference being had to the accompanyingdrawings making a part of' this specification, inwhich- Figure 1 is aplan view of' the apparatus employed by me for odoratin g liquids orother substances; and Fig. 24 a vertical cross-section in the line :v mof Fig. l. The covers of the apparatus shown by Fig. lare removed inthis view;v

The object of my invention is to odorate pure spirits, or othersubstances not liquid, by passing air, at a suitable temperature, andhaving a proper degree of moisture, first through any desired odoratin gsubstance, and

. thereafter through the substance to be odorated, as will behereinafter described.

In the drawings', A represents a tub of' proper dimensions, having aclose-fitting cover, and is provided with a coil of pipe, f, the outerend laof whichcoil extends'iintothe tub near its bottom, from whichpoint the coil rises to nearly the top of the tub as at a', at

which point it passes through the tub A and enters an adjacent tub, B,at the same height, and thence passes down to the bottom of the tubB andaround the interior thereof in the form of a coil, f1. An adjacent tub,C, is provided. with a pipe having a coil, f3, around its interior, asshown, and which, rising to the height of the tub, passes th'roughthecover 7c, and so bent, as atfz, that the outer end of such bent portionmay pass through a` close tting perforation in the cover of the tub B,and thus communicate therewith. -A like pipe, as shown at f4 and f5, isprovided for the tub D, and in like manner is made to communicate withthe tub C. And in a similar manner a coil of pipe, as at f6 andf7, inthel interior of the tub E, is made to communicate with the tub l),which coil has its lower outer end, as at g, extend through the lowerThe lower ends a2 of the several coils are closed, but apertures, as atb, are made in the coils on .tents of' such tub.

the bottom of the tubs B, G, and D, for the escape of' heated air intoand through thecon- In the operation of' the apparatus, I ll the tub Awith water, heated toa temperature sufficient Vto heat air, which by anyproper means may be forced through the coil f at its outer end a. lThiscoil should be of' sufficient length within the tub A to readily andeffectually transmit the heat of' the water'to the air passing throughthe coil. B is thetu'b for saturatin g the heated air with moisture,after pipe f1 will be compelled to pass through the water, andthusabsorb or become saturated with' moisture. The odorating substance isplaced in the tub O, the tub being more or less filled therewith,according Ato the degree of' strength of odor which it is desirable toimpart to the substance to be odorated. The air having become saturatedby being forced through the water'in tub B, escapes therefrom throughthe pipe f2 f3 into the bottom of' the tub O through the perforationsb,'and so mingles with and passes through the odorating-substance placedin said tub, and thence escapes through the pipe f4 f5 and perforationsb into the tub D, which tub is filled more or less with the liquid orsubstance to be odorated. The heated and moistened air heilig forcedthrough the odorating subst-ance in tub C, readily becomes charged withthe odor of' the odorating vsubstance placed therein, and in passingthrough the pure spirits or other substance placed in tub D, impartsthereto the odor with which it has becomecharged in itsA passage throughtub C. After the air has passed up through the pure spirits or othersubstance contained in the tub D, it finally passes off through acondensing-coil of pipe f6 f7, which is made to communicate with thenforced through the series of tubs and coils to the outlet-coil in tub E.

What I claim is- 1. The process described for odorating liquors andother substances, consist-ing` in saturating heated air with aqueousvapor, and passing` such air through an. odorating subY stance and intoor through a liquid, or other substance to be odorated, substantially asdescribed.

2. I claim the combination of a heater, a

Water-bath, an odoratng tank, and a containing tank for holding thesubstance to be odorated, and connecting-pipes, substantially as and forthe purpose described.
